Toner consumption

Depending on the type of printer driver you have, you may be able to select a “draft” mode which uses about 50% less toner, thereby extending the life of the toner cartridge. This is only available using printer driver properties when printing or making copies from the software.

Paper use

Depending on the type of program you use, you may be able to print 2 or 4 document pages on each printed page. This “N-up” printing practice and the printer’s manual duplex capability (two-sided printing) reduce paper usage and the resulting demands on natural resources.

The design of this HP LaserJet printer facilitates the recycling of:

Plastic parts have marking according to international standards that enhance the ability to identify plastics for recycling purposes at the end of the product’s life. The plastics used in the product housing and chassis are technically recyclable.

HP toner cartridges/photoconductive drum

In many countries, this product’s toner cartridge/drum can be returned to HP using the prepaid shipping label and instructions included inside each new HP toner cartridge box. If your country is not listed in the recycling guide, call your local HP Sales and Service Office for further instructions.

HP cartridge recycling program

Since 1990, the HP LaserJet Toner Cartridge Recycling Program has collected more than 12 million cartridges that otherwise would have been discarded into landfills or similar facilities. Once a cartridge is returned through the prepaid return program, it is disassembled, and reusable components and the plastic housing are cleaned and inspected for quality conformance. After passing strict inspection procedures, materials such as nuts, screws, and clips are reclaimed and used to produce new cartridges. Remaining materials are melted down and used as raw materials for a variety of other products. Over 95 percent of the weight of returned materials is recycled. For more information in the U.S., contact the HP LaserJet Supplies Website at: http://LJsupplies.com/planetpartners International customers can call the local HP Sales and Service Office for further information regarding the HP Toner Cartridge Recycling Program.

Printer and parts

Design for recycling has been incorporated into this printer and its accessories. The number of materials has been kept to a minimum while ensuring proper functionality and high product reliability. Dissimilar materials have been designed to separate easily. Fasteners and other connections are easy to locate, access, and remove with common tools. High priority parts have been designed to be accessed quickly for efficient disassembly and repair. Plastic parts have been primarily designed in two colors to enhance recycling options. A few small parts are colored specifically to highlight customer access points.

HP provides a product return system for customers in Germany. Many of the functional parts are recovered, tested, and reused as fully warranted service parts. Used parts are not placed into new product manufacturing. Remaining product parts are recycled, if possible. For product return information, contact:

Hewlett-Packard GmbH Wertstoffzentrum Fronackerstr .30 71063 Sindelfingen

Toner cartridge information

Toner cartridges contain components that are sensitive to light, temperature, and humidity. Follow the recommendations in this section to ensure the highest quality and longest life of HP toner cartridges.

Keep the HP LaserJet 3100 product within the following environmental conditions for optimum performance.

Storage conditions

Toner cartridges are affected by their environment. Packaging protects toner cartridges from light and increases storage life. It is important to store cartridges in their original packaging until ready for installation.

When storing cartridges in a warehouse or work area, make sure the storage place meets the conditions specified in Table 6.

Storing opened toner cartridges

Because cartridges do not have shutters to cover the laser beam access slot, they should be kept inside the HP LaserJet 3100 product until empty. Toner cartridges that have had the toner sealing tape removed are also more vulnerable to environmental extremes.

If a toner cartridge must be removed from the HP LaserJet 3100 product, always store the cartridge:

● Inside the protective bag in which it was originally packaged.

● In a dark cabinet, away from direct sunlight.

● Correct side up and in a horizontal position (not standing on end).

● Away from ammonia or organic solvent fumes.

CAUTION Never ship the HP LaserJet 3100 product with a toner cartridge

installed. Excessive vibration during shipping can cause toner to leak, contaminating the product and possibly damaging the drum. Never expose a cartridge to direct sunlight or to room light for more than a few minutes. Bright light can permanently damage a toner cartridge.

Cleaning and maintaining the equipment

WARNING!

CAUTION

Note

Before you perform these steps, unplug the printer to avoid shock hazard.

To maintain quality, thoroughly clean the HP LaserJet 3100 product:

Any time a new toner cartridge is installed.

●

After printing approximately 2,500 pages.

●

Whenever print quality problems appear.

●

Clean the outside of the printer with a slightly water-dampened cloth. Clean the inside with only a dry, lint-free cloth (such as lens tissues).

To avoid permanent damage to the toner cartridge, do not use ammonia-based cleaners on or around the HP LaserJet 3100 product.

When cleaning around the printer door area, avoid touching the heating element. It might be very hot and can cause burns.

Do not touch the surface of the transfer roller. Contaminants on the roller can cause print quality problems.

Be careful not to touch the glass surface of the image sensor. If you inadvertently touch the glass, clean it according to the instructions on the following pages.

Cleaning the document scanner path

Clean parts of the document scanner if the ink on items you are scanning can be smudged with your hand, or if the parts have excessive amounts of dust or dirt on them. Also clean these parts if there are smudges or other marks on documents or scans of documents.

WARNING!

Before cleaning the HP LaserJet 3100 product, disconnect it from the power source.

1 Open the document release door. 2 If the white sheet is dirty, clean it

with a dry cotton swab. If there is still something on the white sheet, dab a swab in a small amount of isopropyl alcohol and gently clean the white sheet.

CAUTION

When you use alcohol, only use a very small amount. Exposing internal parts to dripping alcohol can damage them.

Maintenance

3 If the glass surface of the contact

image sensor is dirty, clean it with a dry cotton swab. If there is still something on the glass, dab a swab in a small amount of isopropyl alcohol and gently clean the glass.

Page 58

Inspect each of the six rollers in the

document scanner area for dirt or debris. Using a lint-free cloth dampened with a small amount of isopropyl alcohol, wipe any dirty rollers using a side-to-side motion.

CAUTION

Do not spray alcohol or any other liquid directly into the HP LaserJet 3100 product. Doing so can damage the product.

CAUTION

As much as possible, avoid touching the white sheet and the glass surface with alcohol.

Near the top, inside edge of the

document release door, inspect the three pressure feet and pad for dirt or debris. If they are dirty, clean them with a lint-free cloth dampened with a small amount of alcohol.

Note

If toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water and the heat of the dryer set toner into the fabric.

Remove the toner cartridge.

Note

If you notice excessive amounts of toner inside the HP LaserJet 3100 product, the toner cartridge may be defective. Use HP LaserJet toner cartridges to ensure high-quality printing and to reduce incidence of excessive toner.

Dab a lint-free cloth in isopropyl

alcohol. Locate the light gray pickup roller

near the center in the opening.

Note

Do not touch the transfer roller. Touching it can reduce the print quality of output.

Cleaning the print path 59

Using a cleaning page

After you have cleaned the printer parts, use this procedure to print and use a cleaning page, if needed. This cleaning page can help remove toner specks on your printed pages.

To use a cleaning page

Place a stack of plain letter- or A4-

sized paper into the paper input bin. (Do not use thick or rough paper.)

For Windows 95, open Windows

Explorer.

- Or For Windows 3.1x, open File Manager.

Open the JetSuite folder (if the

JetSuite Pro software was installed to the default location, the path is “C:\JetSuite”).

Note

If you do not have access to JetSuite Pro software, a cleaning page is available from the HP LaserJet 3100 product web address: http://www.hp.com/support/lj3100

Double-click

the cleaning page. When the document opens in the

JetSuite Pro software, click the link icon bar at the bottom of the dialog.

After the cleaning page has printed,

remove the stack of paper from the paper input bin.

Using a cleaning page 61

to open

Page 63

Place the cleaning page into the

paper input bin, top first, face down. Print a different file.

Inspect the page. If there are no

shiny, black spots on the page’s black strip, the print path is clean. Discard the page, and the procedure has been completed.

If there are shiny, black spots on the

page’s black strip, toner has been cleaned from the print path. Discard the page. Repeat steps 1 through 9 until there are no shiny, black spots on the page.

Note

If toner specks appear often and there is a frequent need to clean the print path, try using a different type of paper, and make sure the paper meets HP paper specifications. If the problem persists, see Chapter 6, “Troubleshooting,” for detailed information about repetitive defects and other image quality problems.
